Thanks for the info. But it appears that the mbean:
org.apache.tomcat.jdbc.pool.jmx.ConnectionPool
is not registered. I found some code that collects info from this bean,
and this mbean doesn't even show up when querying jmx in Tomcat. I am
running Tomcat 8.5. I've tried googling and couldn't find any info on
how to activate this bean. Can someone explain how to make it show up?
Thanks.

I followed the instructions to enable JMX on Tomcat. I added the
following lines to java config:
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=8083
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Djava.rmi.server.hostname=localhost
I opened JConsole localhost;8083, and it connected. I can see CPU, heap,
classes, and thread graphs. When I look at the MBean tab, I see a Catalina
entry and a "DataSource" entry below that. Expanding that gives me a ton
of attributes, operations, and notifications for my various datasources.
That's fine. But what I want is to be able to do is monitor a graph of the
connection pools. I saw an example graph on a 3rd party web post from
several years ago. But I can't find anything that shows connection pool
usage graphs in my JConsole.
What am I missing?
Thanks.

Maybe you can try jvisualvm instead of JConsole.
The binary is in the /bin folder of the JAVA_HOME.
You can also add plugins to it. Maybe there is a plugin for your need.
